Tom Curtis at 10:15 AM on 5 August 2012IPCC is alarmist
Allowing Krisbaum his best argument, he relies on the "research" summarized at the inaccurately named NoConsensus website. Their "citizen audit", ie, a review by a group of biased, unqualified people, has found that a total of 21 chapters of the IPCC AR4's 44 chapters receive a failing grade of F, based on percentage of grey literature used. Of course, it is very clear that that is not a troubling statistic. To start with, something, they take great lengths to downplay is that WG1, as a whole receives an A (93% peer reviewed) in their arbitrary marking system. Based on their methodology, therefore, they should have every confidence in the IPCC AR4 WG1 report. Second, they entirely fail to adress the quality of the grey literature used. Among items listed as "grey literature" are academic monographs, academic books, CSIRO and other scientific institution reports, major government reports, and of course, anything produced by the IPCC itself. In fact, I have so far not come across a single item of "grey literature" that would not be cited without qualm in any academic literature. The website does mention citation of press releases, which would clearly be inappropriate - but do not give any indication of the frequency of citation of such dubious literature. I have heard of, but not investigated just one example of such dubious reference in 18,500 references (ignoring duplicate citations). The failure of the site to list frequency of citation of news releases, or papers by "advocacy groups" like the World Wildlife Fund suggests to me that such a listing would severely damage their case. Nor is it obvious to me why the IPCC should reject out of hand any information from such groups. Finally, the group provides no measure of reliance on grey literature. The IPCC must consider all views on the subject, and therefore consult (and hence include as references) some truly atrocious works. Therefore, the mere citation of a reference in no way shows that the views in that reference, or facts adduced in it, have been accepted by the IPCC report. A serious attempt to audit the IPCC on this point would need to not only show that the IPCC cited grey literature of dubious quality, but that facts contributing to the conclusions of the IPCC where obtained solely from such unreliable grey literature. No attempt to show such a pattern of reliance on dubious sources has been undertaken. Again, I suspect strongly that is because deniers have tried unsuccessfully to impeach the IPCC reports as generally inaccurate, and know the futility of such an approach. Consequently they take an indirect approach in which they can obfusticate the difference press releases and Academic textbooks to create a false impression of unreliability. -

Rob @53 - I agree, except that Watts et al. isn't submitted either! And frankly it's in such bad shape that if they were to actually put in the time to do the analysis right, I doubt if it would be submitted in 2012 either. We have discussed the Parker (2006) paper mentioned by neal @54 here. -
Tom Curtis at 08:56 AM on 5 August 2012IPCC is alarmist
Michael Sweet @70, it is possible that Krisbaum's objection to a recent recipient of a doctorate becoming a Lead Author is an exagerated idea of what Lead Authors actually do. In the IPCC writing process, Lead Authors are one of a team of five more Lead Authors, each team lead be two or three Co-ordinating Lead Authors. Consequently, lead author does not get to write a chapter by themselves, and are not even the most senior people involved in writing a chapter. It is true that a Lead Author might be asked to write a particular section within a chapter based on particular expertise, but such a request would be decided upon by the Coordinating Lead Authors and other Lead Authors in a meeting, and the resulting section would be subject to review by the full authorship group prior to completion of the first order draft. The upshot is that a Lead Author, despite the exalted title is just a relatively minor member of a team. As such, objections to recent recipients of doctorates being Lead Authors just show a lack of understanding of the process involved. -

Krisbaum @29, I grew up (mostly) in Mount Isa, Queensland. The ore in Mount Isa has a high sulphur content, a fact made plain to us when the prevailing easterly wind failed, and the plume from the copper smelter stack (red and white hoops) settled over the town, resulting our filtering out the SO2 inefficiently with our lungs. Occasionally it would rain with a westerly wind, in which case the SO2 was filtered out efficiently by the rain water, killing every rose bush in Mount Isa with a dilute acid. The effect of rainfall with the prevailing easterlies can be seen in the barren western hills behind the mine, stripped even of the hardy spinifex seen in the foreground. The reduced vegetation was apparent up to 30 miles west of the mines:
The relevance of this? When I was relatively young I read of a study in Mount Isa Mines internal magazine, Mimag, which traced the flue gas from Mount Isa by its isotopic composition as far as the coast of Africa. I believe it was the west coast of Africa, meaning the gas had crossed most of Australia, the Indian Ocean, and then Africa itself to come to the Atlantic. I'm not certain about the west coast, however, although I am certain about it reaching Africa.
Now, given one certain instance of industrial SO2 emissions travelling a third of the way around the world, are you going to seriously argue that industrial SO2 emissions from Europe or North America can't reach Greenland?
Yeah, I know. Mimag is grey literate so any information in it can be ignored by you whenever you don't like the consequences - never mind that we take mere blog posts as law when they criticize the IPCC.
So, how about we take a different approach. When you identify the major source of SO2 within 10 km of the GRIP drill site, and how that source miraculously synchronized its emissions with European and North American industrial emissions, I'll believe the SO2 in the ice cores did not come from industrial emissions. If you cannot identify that source, however, I will treat your suggestion that the ice cores do not provide a record of European and North American industrial emissions of SO2 with the scorn it deserves.

nealjking at 07:42 AM on 5 August 2012Watts' New Paper - Analysis and Critique
About the UHI issue: Parker (2004) studied the question of the urban heat island effect and its impact on the temperature trends, by segregating the measurements into two groups: windy-day measurements and calm-day measurements. His conclusions: - On calm days, temperatures run higher than on windy days. The implication is that there is indeed a UHI effect, but a good wind blows it away. - Now if you study the trends for the windy days over the decades, and the trends for the calm days, they are essentially the same: the increase over the study period is the same. So the UHI doesn't seem to have been growing in coverage. For me, this seems to be pretty direct evidence that even though there really is a UHI effect, it is not contributing towards misleading us about temperature trends. Maybe cities are just not expanding fast enough. -

R. Gates at 06:50 AM on 5 August 2012BEST Results Consistent with Human-Caused Global Warming
Excellent post. Should be a must read for anyone still open minded about the extent of human impact on the climate. And regarding that, the discussion of what levels of CO2 is "safe", related of course to prevent some catastrophic breakdown in the biosphere, atmosphere, and ocean systems supporting both humans and other creatures, what is absolutely critical here is a wholistic approach-- true Anthropocene Management. Increasing CO2 levels are just one of the many ways humans are altering this planet, and have been for many centuries. In a wholistic approach, we would look at not just CO2 but land uses, methane, the nitrogen cycle, water use, etc. Thus, while it might be good to pick a general target of CO2, at say 350 ppm, it should be part of an overall Anthropocene Management effort that looks at all the ways humans alter the planet of which controlling CO2 levels is just one aspect. My bigger fear related to this is that things will get out of control faster than most might imagine, leading to ever greater instability in governments and societies around the world. You might see reactionary governments come to power who have no interest in climate control or the instability might cause some to "go it alone" in terms of attempting to geoengineer the planet. We could have geoengineering efforts that end up doing more harm than good. It would be like having 10 different doctors independently treating a patient without any consultation with each other. This all could be very counter productive of course. -

Trent1492: one way to refer to a paper is by the author(s), and the year it was published. see for example the reference to "Schaal et al. 1977" in the article. in this case, Bernard is implying that they're somewhat jumping the gun when they assuming that 5 months will be sufficient to get this particular mess into a publishable state. -
Philippe Chantreau at 06:10 AM on 5 August 2012IPCC is alarmist
Krisbaum's difficulty in obtaining reliable information is transparent in others of his unsupported statements: "it is fairly common knowledge that aerosols do not travel far from their source typically 10km or so. You need localised measurements to get any kind of global pattern." This assertion is not supported by any scientific reference in the post. Anyone looking at a satellite picture of China's dust traveling over the Pacific will come to the conclusion that saying "10km or so" is so removed from reality as to indicate deep ignorance of the subject. Earlier Krisbaum was mentioning the lack of a historical depth to the science of atmospheric aerosols. If one does explore the subject, however, one of the first things to be found is 19th century research centered on studying the reports of ships receiving dust from the Sahara while thousands of km away in the Atlantic. Not 10 km, thousands. This remains a common occurrence, that can easily be seen on satellite pictures. On this one from NASA, the dust crosses the entire Atlantic: http://earthobservatory.nasa.gov/IOTD/view.php?id=44169 Th entire Atlantic, not 10 km. It should be noted that this is dust picked up from the ground, not injected directly in the stratosphere by a volcano. How quickly that latter type travels around the world has already been studied extensively. I do not believe that it is even necessary to post any reference on that, as it takes only a few seconds on Google to find an entire list. The picture of Saharan dust above took me less than 10 seconds to find. In light of this, it is safe to say that this statement: "it is fairly common knowledge that aerosols do not travel far from their source typically 10km or so" is total nonsense that can not possibly form in the mind of anyone actually trying to get information on the subject. Now, let's examine this: "You need localised measurements to get any kind of global pattern." There is a contradiction of terms in the first place, but let's consider that what was meant was something like: you need many, gridded local measurements to get etc etc. It still makes no sense. Aerosols that do not reach the upper atmosphere have no global climate influence. The impossible-to-pronounce- Icelandic volcano that disrupted air travel not long ago did not create a real forcing because aerosols did not go high enough. Having a local record will tell only how some aerosols could have affected that local area. Records from Greenland, where there are no local sources, show the amount of well mixed aerosols, that are present in the atmosphere at large and can be a global forcing. -

John B - the Great Barrier Reef may be entering a time of great danger. Not only is ocean acidification bubbling away in the background, but a return to an El Nino-dominant period will probably bring on mass coral bleaching. Not good for a reef already losing coral cover year-by-year due to pollution, disease and crown-of-thorns outbreaks. You'd expect an Environment Minister to be.....concerned about the environment. -

Daniel Bailey at 04:17 AM on 5 August 2012Unprecedented Greenland Ice Sheet Surface Melt
I did get a response back from Dr. Box agreeing that Greenland surface melt "150 year cycles" should be looked into. He further added that the 1 degree C summer temperature increase in the period of instrumental observations, continuous for west Greenland since 1840 (173 years), make melt episodes more likely. As an FYI, Dr. Box has a blog post update of relevance, here: http://www.meltfactor.org/blog/?p=677. In which can be found this excellent graphic:
The warming of the GIS during the 1930's is notably less than that warming being experienced by the GIS today.

michael sweet at 02:21 AM on 5 August 2012IPCC is alarmist
Krisbaum, It is difficult to discuss the IPCC with you because you appear to have no understanding of how the IPCC works and what its intended goals are. The Intergovernmental PCC was formed to inform the world's governments about the possibility of climate change. As such governments choose the experts who write the reports. Who do you suggest would be better to choose the experts- you? Your suggestion that someone else should choose the experts is absurd, there is no-one else who could choose them. In any case, if you do not like the experts chosen you can complain. While I have not heard of anyone replaced because they were complained about I would be surprised if no-one has been removed from a position. The experts include scientists from the oil industry. I am astonished that you complain that an expert had only earned his PhD two years before he was made a lead author. It sounds to me like he was a rising scientist who was willing to take on a job. Experts agreed he was qualified, what data do you have to contradict their assessment? I note this person wrote the 1994 report. If you have to look that far into the past to find a complaint the reports since then must be perfect. Your suggestion that governments should not have any involvement in the SPM is also absurd. The whole purpose of the IPCC is to develop a consensus report for governments to use. The SPM is a political document based on the underlying scientific report. It is the responsibility of the governments of the world to ensure an accurate summary is made. As I recall, the US representative was booed because of some statements he made. The USA generally tried to make the SPM less sure than WG1 and other , more progressive countries, fought to keep the SPM more true to the scientific report. Complaining that a political document was compiled by governments is just arguing for arguments sake. The scientific report has been drafted and reviewed several times before the SPM is written. Final edits are small. Changes are agreed on by expert reviewers. You are arguing that if the report is not perfect, by your ever changing standards, it is not dependable. You will never be pleased since you can just change your standards again. In many countries reports are written and published in different ways than we do in the USA, Europe and Australia. In these areas the gray literature is where the data is. When the IPCC experts used these reports they review them before citing them. You are insisting that the IPCC produce a perfect report, 3000 pages long, in a world that is not perfect. Why do you accept denier garbage that has errors in every paragraph when the IPCC must be perfect? -
Tor B at 01:12 AM on 5 August 2012BEST Results Consistent with Human-Caused Global Warming
#23 ranyl pretty much speaks my mind. Human discontent, such as demonstrated by the Arab Spring, has already been connected to AGW. I once made a bumper sicker that read "Peace by 1927" because it sounded cool (I'd just read 1984, and like it's author, I reversed the current date.), and a history buff told me that it was about the right date to prevent WWII. So now, as a single issue voter, I might say "Peace with 350 ppm". At least this is something we can theoretically get back to. As it says in Deuteronomy "so that you and your children may live." -

Paul from VA at 00:28 AM on 5 August 2012Is Greenland close to a climate tipping point?
@ 4 Chris G You're exactly right. In fact, massive ice loss due to darkening as the mixture between ice and dust (lag) becomes more dusty as ice melts has already been observed elsewhere in the solar system. This process is part of what is thought to have caused Saturn's icy moon Iapetus to have one side which is 10x darker than the other. ref: Spencer and Denk 2010 -

On ABC radio PM program 4 Jun 2012:- MATT WORDSWORTH: The Great Barrier Reef Marine Park Authority issued a report in 2009 citing anthropogenic climate change as a priority issue for the reef. But Queensland's Environment Minister Andrew Powell is not convinced about the role of humans. ANDREW POWELL: Look, I believe the climate is changing; I am still to be convinced of the degree to which we are influencing that. But having said that, are we polluting the environment? Certainly. Are we using a non renewable source of energy? Certainly. Do we need to address both of those factors? Most definitely. As environment minister he should be aware that scientists have positively identified (via carbon isotopes) the source of this additional CO2; it originating from the burning of fossil fuels. -

The NSW Deputy premier ANDREW STONER: On ABC radio PM program 4 Jun 2012:- MATT WORDSWORTH: New South Wales' Deputy Premier Andrew Stoner recently voiced his concerns about climate science. Three weeks ago he attacked the Climate Commission's report, The Critical Decade, which predicted a rise in heatwave events and flash flooding. ANDREW STONER: This is alarmist, we've heard predictions of all our dams drying up in the past, we've heard predictions of the Central Coast and other coastal parts of the state going underwater, the polar ice caps melting. I'm sorry, none of this has happened so unless he's got some new evidence, I think the average person would be a little sceptical. An example of dismissing the issue by assuming an unrealistic timescale on the predicted possible occurrence of these dire events. He should be reminded of the planetary timescale on which climate change occurs. -
JohnB6223 at 21:05 PM on 4 August 2012Is Greenland close to a climate tipping point?
Thanks 17, 18 and 19 for your reply. I consider it wishful thinking that "melting could stop"; especially in view of climate warming events over recent years. The adventurous statement by Kurt H. Kjær "the current thinning of the ice sheet is likely to ease within an 8-year period." will unfortunately be fodder for vested deniers. -
Rob Painting at 19:56 PM on 4 August 2012IPCC is alarmist
krisbaum - I counted 5284 citations of peer-reviewed scientific literature in Working Group 1 of the 2007 IPCC report (the physical science basis). The 10 citations of grey literature therefore equals 0.19 % of the citations in that report. This is in stark contrast to your claim @ 40: "Something like 1/3 of the references in the last report are grey literature - WWF reports, Greenpeace, news, un-peer reviewed.. etc.." Your claim is total bunk. -
Bernard J. at 18:09 PM on 4 August 2012Watts' New Paper - Analysis and Critique
One of the things that's been amusing me about this 'paper' is that it's being referred to as Watts 12. There's a huge assumption here that it will actually find publication this year. Given the extremely poor quality of the first draft, and the length of time it would require to salvage anything from it, let alone to re-write, submit, review, refine, accept, and print any future version, the '12' appellation is optimistic indeed. -
Bernard J. at 18:04 PM on 4 August 2012IPCC is alarmist
Krisbaum. You appear to have a very serious problem with 'grey literature'. Given (conservatively) that more than 99.9% of the denialist literature is at best 'grey', what from that body of commentary do you accept, and why? On the matter of the IPCC's use of grey literature, with which of their references do you have particular issue? The most obvious one that I can think of is the 2035 Himalayan glacier melt gaff, which appears to have originated with a tyographic error in reproducing the date 2350. Tellingly, the offending paragraph did not alter conclusions elsewhere in AR4, and if this is as serious as errors go in a document of many hundreds of pages, then even the most stringent scientific publisher would be proud. -

Tom; thats news to me! I havent seen that section before. Thanks! Here's what Pachauri has been saying--> “People can have confidence in the IPCC’s conclusions…Given that it is all on the basis of peer-reviewed literature.” – Rajendra Pachauri, IPCC chairman, June 2008 “The IPCC doesn’t do any research itself. We only develop our assessments on the basis of peer-reviewed literature.” – Rajendra Pachauri, IPCC chairman, June 2007 “This is based on peer-reviewed literature. That’s the manner in which the IPCC functions. We don’t pick up a newspaper article and, based on that, come up with our findings.” – Rajendra Pachauri, IPCC chairman, June 2008 i dont think i will write anything more to respond, all the links/evidence I give just gets deleted. Good luck with your climate studies. -
DSL at 14:41 PM on 4 August 2012IPCC is alarmist
To add to Tom's comment, the following passages are from the June AR5 WG1 Progress Report: "The IPCC provides governments with a clear scientific view of the current state of knowledge about climate change, its potential impacts, and options for adaptation and mitigation, through regular assessments of the most recent scientific, technical and socio-economic information published worldwide. These assessments are policy-relevant, but not policy-prescriptive." (emphasis mine) and "Working Group I, which covers the physical science of climate change, received 21,400 comments from 659 experts worldwide in the expert review of its first order draft, which ran from 16 December 2011 to 10 February 2012. Working Group I authors are now considering these comments, as they work on the second order draft, which will be available for expert and government review from 5 October to 30 November 2012." -
Tom Curtis at 14:10 PM on 4 August 2012IPCC is alarmist
Krisbaum, the with regard to the IPCC AR4 Working Group 2 report, the IPCC states:"The Working Group II Fourth Assessment, in common with all IPCC reports, has been produced through an open and peer-reviewed process. It builds upon past assessments and IPCC Special Reports, and incorporates the results of the past 5 years of climate change impacts, adaptation and vulnerability research. Each chapter presents a balanced assessment of the literature which has appeared since the Third Assessment Report[1] (TAR), including non-English language and, where appropriate, ‘grey’ literature."
(My emphasis) Your thesis that the IPCC claims to not use grey literature is, therefore, clearly false. The IPCC has clearly delineated procedures for the use of grey literature. Clearly you are arguing a straw man. If you would actually like to address the issue of the quality of references used by showing scientific flaws in the references that have made it into the reports, you might have something interesting to discuss. As it stands your are simply trying to denigrate the reports by innuendo. -

Right, krisbaum, and I am asking you if you think the PhD theses lack quality because they haven't been peer-review by journal reviewers for a journal. Have they been reviewed by experts? If you've been through a PhD defense, then you know the answer. It's entirely possible that the review was performed by scientists who do review work for journals. And I am quite certain that the IPCC reviewers didn't simply accept the theses as the equal of peer-reviewed, published work. The IPCC has used grey literature. They point this out themselves.

DSL- my original point was that the IPCC does not produce a report solely on peer reviewed literature. It advertises the fact that it does - agreed? Its not whether the science is good or bad in the grey literature, you cannot tell the world your report is only based on peer reviewed literature - when in fact it isnt.Moderator Response:[DB] Your citations are insufficient because you fail to demonstrate for each which specific portions of WG1 they are based on and why the reference you cite fully fulfills the role of citation for that section.

krisbaum, you assign blanket mistrust to the category "grey literature." I guess you assume that because the PhD thesis was not published, it must not be trustworthy. Something must be "wrong" with it. You should let the thesis committees for these individuals know that you've caught on to their fraud. What is your assessment of these pieces of "grey" literature? Are they good science? PhD theses/dissertations are not published for a variety of reasons. -

Actually, your very first comment in this forum contained sufficient vitriol towards a regular member of this forum that the entire comment necessitated immediate deletion. Nevertheless, can all participants exercise more discretion in their comment formulations, please?

Rob, I think it would fairer to suggest the krisbaum is reading frothing-at-mouth denialist sites and prefers to believe what he is told there. krisbaum, you are implying lead authors have "vested interests" in results. What is the basis of this belief? By the way, I would be perfectly happy for Exxon staff to be reviewing and writing what they would so long as they are Exxon's scientists. I am oil man. By your interpretation of the world, I should be a rabid anti-AGW activist because AGW threatens my current position. In fact, I mostly find widespread acceptance of the IPCC conclusions among my colleagues and client's scientists. -

Don't expect SkS readers to fossick around in that mess. Cite one portion from WG1 that is based on 'grey literature.' If you're familiar with the details it won't take long. We're waiting............. -

How about showing us a portion in WG1 (the scientific basis) that is based on 'grey literature.' Failure to do so will lead to the inescapable conclusion you simply made that up. -

DB - i cant furnish your request unless I know what your interpretation of 'reputable' is ????Moderator Response: [DB] Either something like a commentary paper in a peer-reviewed journal or showing directly which section of WG1 was based on which specific piece of grey literature. It was your statement; it is incumbent upon you to be able to furnish documentation supporting it...or to withdraw the assertion. -

Just saw this little gem over at WUWT: Ric Werme says: August 3, 2012 at 1:58 pm ........... It might be interesting to take pre and post homogenized data and see how that displays and analyzes. Is there anyone here who can help this poor guy out? ;)
